Isotope is a term that refers to the different individual atomic masses that a particular element exhibits. For example, the element carbon most stably occurs in nature as carbon-12, indicating an atomic mass of 12. However, an common unstable isotope, carbon-14, popularly used by scientist to date artifacts, has an atomic mass of 14. Unstable isotopes are known as radioactive isotopes, and decay over time to more stable isotopes.
